BENICIA — A Benicia Middle School teen seen being attacked by two of her peers last week in a video posted on YouTube was in school Monday as district officials vowed to develop a plan to better protect students.

The 13-year-old victim, who is not being identified because she is a minor, had a “good day” Monday, Benicia Unified School District Superintendent Janice Adams said.

Police said she sustained minor neck and head injuries from the beating attack. No weapons were involved.

The two girls suspected in the attack — 12- and 14-year-old Benicia Middle School students — were arrested over the weekend and remained in custody Monday afternoon, Adams said.

District officials are developing a plan to address violence and the use of the Internet to harm others, Adams said.

The video of the alleged attack was removed from YouTube at police request, police Lt. Mike Daley said in a press release.

Neither Adams nor Benicia school board president Rosie Switzer could recall an incident where an attack was videotaped. Both added that, while fights do occur, they are not common in the middle school.

The attack is said to have taken place on a field at Robert Semple Elementary School on Saturday after the two suspects lured the victim by saying they had some of her property, police said.

The suspects are also said to have attacked the victim on Wednesday at the same site. All district schools were closed last week for Thanksgiving. It was unclear why the girl returned Saturday following the alleged attack on Wednesday.

Though the incident generated media attention Monday, prompting Adams to hold a mid-afternoon press conference, the superintendent said she had not received a single parent phone call.

Adams and Switzer said the incident was saddening, and they hope students will treat each other better.

The district is planning a parent night about cyberbullying.

Adams also said that a school psychologist, teachers and staff are resources for students.
